Although I have seen some improvement in Plasma with Wayland over the last few months, it is still far from usable for me. When logging in to the Wayland session it seems to start up well enough. (Better than before when I only ended up with a black screen).
But, the first thing that indicates there is something wrong is the extremely lagging cursor. It drags behind the mouse movements. After just a few minutes the whole system comes to a halt. System monitor shows that the four core CPU behaves extremely erratic, fluctuating between 0 and 100%. The memory starts normal, but even without any activity going on, memory use goes gradually up till it uses almost all of the 8 Gb. After that everything freezes, and I have to hard reboot.
The whole system is up to date. I am using an Asus K52. Intel 4x core i5-3210 CPU @2.5Ghz, 8 Gb RAM.
Any ideas what causes this?
